All postsReference-Free Quadrature Filters For The Sine Benchmark
Deterministic quadrature ADF and Power-EP baselines showed that much of the nonlinear filtering gap was algorithmic, not just amortization.
When Mixtures Beat Local ELBO In Nonlinear Filtering
Small strict mixture filters with IWAE and FIVO-style objectives closed much of the nonlinear calibration gap while staying reference-free.
Repairing a Nonlinear Strict Filter Without Reference Targets
The nonlinear sine-observation benchmark exposed ELBO under-dispersion, then a joint ELBO, predictive-y, and masked-y objective partially repaired it.
Variational Filtering, Rebuilt From the Linear Case
A scalar linear-Gaussian benchmark made the VBF edge-factor implementation auditable before moving to nonlinear filtering.
